Description

DNASE1, also known as Deoxyribonuclease 1, is an endonuclease found in the zymogen granules of the nuclear envelope. Responsible for DNA fragmentation and cell death during apoptosis, DNASE1 binds to G-actin and blocks actin polymerization. Mutations in DNASE1 cause systemic lupus erythematosus (SLE), an autoimmune disease causing inflammation and tissue damage. DNASE1 is also known to treat symptoms of cystic fibrosis.
